"The development timetable is on track, and with space from just #10 per square foot, interest has been understandably high. The lights switch on is a great indication that very soon, Fort Dunlop will be open for business."

Simon Stokes, business development manager for Warwick-based Ace Signs Group, suppliers of the signage, said: "The letters will bring light and a sense of location to the immediate surrounds, and will normally be lit using white lighting.

"They also have the capacity to be illuminated with colour, drawing from a palette of millions of different shades. This will be used to support brand or tenant launches, as well as to potentially mark national days such as St George's Day, with red and white."

The site is being converted into a mixed-use complex as part of a huge #45 million redevelopment programme. The 350,000 sq ft site has already created 1,000 jobs, with developers aiming for around 2,500 once the building is complete.

The scheme will be officially launched at an opening ceremony before Christmas with Urban Splash aiming for a rolling programme of office occupation.
